Abstract
Use of an aperture in the reconstructed beam in reconstruction of multiple holograms increases selectivity beyond that realizable by spatial multiplexing so as to permit differentiation of overlapping images. 'Aperturization' is suitably used for differentiation in the y-direction in shift holography, depending on Bragg selection in the x-direction.
